Hi! I'm Garrett Albright, and for over five years, I've been maintaining the Pathologic contributed module, which provides an input filter for correcting URLs in content. During those years, I've come to acquire a good level of familiarity with Drupal's text formatting system, and now I'd like to share that familiarity with you.
Your Drupal site probably uses the complex, unglamorous text formatting system several times a day at the very least. Wouldn't you like to learn more about how it works and how you can make it work for you?
The proposed session will cover:
How and when the text format system works
How input filters "stack" and interact with each other
How and when the text format caches its results, and how not to get tripped up by it
How to develop a simple input filter for Drupal 7
…and make it more complex by providing user-changeable settings in a settings form
